“…The goal, however, is to eliminate sets of inferior expansion plans using bounds determined from a limited enumeration. The general properties of branch-and-bound techniques are described by Garfinkel and Nemhauser (1972), Lawler and Wood (1966), and Mitten (1970). Marks and Liebman (1970), Brill and Nakamura (1978), Nakamura and Brill (1979), Ball, Bialas, and Loucks (1978), Efrovmson and Ray (1966), and Morin (1970) propose branch-and-bound methods for selection of the optimal combination of discrete capacity-expansion alternatives.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
